urmsunme DEVICE.

To all whom it may concern i Be it known thatl, MATTHEW Mourns, a citizenof the United States,"residing at Nor-' wich, county of ew'London,State of (1011-. necticut, have inventedcertain newand use ful Improvements in Measuring Devices, of which the following is a specification.

This inventionrelates more especially to devices for measuring the amount of goods passing throughorfrom a machine or pr d-uced by a machine, The primary object of my invention is to provide an improved construction, Combination and arrangement of pants in a device of this character, whereby the amount of movement or production of goods may be accurately measured, and an undue "waste of goods avoided. Certain features of this device which are hereinafter explained, reside in simple and feflbctive means for accurately predetermining theextent of goods to :be produced by or passed through the machine, thus making it unnecessary to uselessly prolong the operation of said machine after the desired result has been. obtained. One object of the present invention is to provide improved means for registering predetermined amounts of goods which are being moved or produced by a niachine. Another object is to provide improved means for cutting out the power or interrupting the movement or production of good-s. ()ther andfurther objects will appear in the specification and be pointed out in the appended claims, reference being had to the accompanying drawings which exemplify my invention in preferred embodiment. In these drawings, the invention is illustrated in anada'ptation to a circular knitting machine which operates the measuring device, preferably by causing the goods or product to pass over an instrumentality, such for example, as a wheel for imparting a relative movement to an in: dicator and scale by means of which the amount of movement or production is to be i measured. In the drawings Figure 1 is a top plan of one embodiment of my invention, in this instance attached to a circular knitting machine;

Fig. 2 is a frontelevation of the same, on an enlarged scale, as said embodiment is seen when viewed from theouter periphery of the knitting machine looking toward the center. i

" Fig. 6 is a top plan view of the same.

According to theembodiment of my. invention shownin Figs. 1', 2, 3 and 1, a bracket 1 is suitably secured to the rotary frame or traveling ,ring 2 of a circular knitting machinelsee Figs. 3 and 4). The

ringZ is provided with a circular rack 3 with which meshes a drivmg gear 4 mounted on a power shaft 5 which may be themain drive shaft of the knitting machine. The knitting machine parts shown on i the drawings are fragments of a well known type of knitting machine which is usually provided with a slidable ring 6 which controls the application ofpower to the knitting machine by shiftinga belt from a tight to a loose pulley or vice versa. Usually,in a circular knitting machine the ring 6 is shifted by hand or by means of an automaticcut-out device which depends for its operation on the uninterrupted supply of yarn, or on conditions around the knitting needles. Ac,

cording to the presentem'bodiment of my invention,-the bracket 1 is provided with a laterally projecting; portion 7 with an up ward'ly defleotedextremity 8 which carries an adjustable scale bar 9. As shownbest in Fig. 2,the bracket '1 carries a stud 10 which is secured in said bracket by means .of a nut 11. Journraled on the stud 10 is a wheel 12 providedwith radially projecting pins 13 which are adapted to-be engaged by the goods 14 which. in this instance are drawn from the lmitting machines Secured to the lateral face of wheel 12 is a strap or band 14 which oarriesa screw 15, said screw being rigidly secured to the strap or band 14 by means of check nuts 16. An indicator arm 17 which is adapted to cooperate with the scale bar 9 to indicate the amount of goods passed over the wheel 12, is provided with a hub comprisingsplit nut sections 18 and 19, the formerbeing integrally formed with the indicator arm 17 while the latter is yieldably connected thereto by means of springs 20 which are interposed between the oa'pseotion 19 and theheads of a pair of studs 21 Whichpass through the cap 19 and the scale bar. Coiiperating with this. feature of the device, is an abutment nut22 which is split on one side of the feed screw 15 and provided with a set screw 23 by means of which it may be rigidly secured to said feed screw 15. At the same time, it may be adjusted to any desired position corresponding to the setting of the scale bar 9 so that the indicator arm 17 will be gradually moved to dotted line position shown in Fig. 4 by coming into abutment with the nut 22 which prevents its further progress along the feed screw. The abutment nut 22 in conjunction with feed screw 15 therefore constitutes positively acting means for forcing the indictor arm 17 to revolve on said feed screw should its grip on the screw be in- I suflicient for that purpose. Referring now to Fig. 4, a pin or post 24 is provided with a reduced end 25 which is threaded'into the traveling ring 2 and at the same time serves to secure the bracket 1 in position on said ring. Depending from the bracket 1 isan arm 26 which carries a pin 27 on which oscillates a latching dog 28 provided with a nose 29 which is adapted to'engage in a recess 30 in the lower end of a sleeve 31 which reciprocates on the post 24 and is provided with a slot 32 by means of which its end'wise movement is limited with reference to a pin 33 which projects laterally from the post 24. As the traveling ring 2 revolves on its axis, the sleeve 31 is retained in its raised position by means of the latch dog 28,:until such time asthe indicator arm 17 has been fed into position beyond the right hand extremity of scale bar 9, according to. Fig. 2, when itb'ecomes elevated into dotted line position, shown in Fig. 4, to engage the latch dog 28, thus serving to withdraw the nose 29 from the recess 30.

Immediately the sleeve 31' falls to its lower position and during the course of the succeeding revolution of the ring 2, said sleeve.

31 will come into engagement with the inwardly projecting arm of' a lever 34 which is pivotally mounted on a post 35 carried by a fixed plate or frame 36 of the machine. The outer end of the lever 34 is provided'with a handle 37 by means of which it may be hand operated when desired. The

inner arm 34 of said lever is provided with a slot 38 through which projects a pin or bolt 39 carried by the slidable ring 6, which, as

hereinbefore stated, is adaptedby its movement to bring the machine to a stop.

Referring now to the embodiment of my invention'shown in Figs. 5 and 6 in order to adapt this attachment for aknitting machine of small radius, or for any other machine in which the arrangement shown in Figs. 1 to 4 inclusive is not adapted, the traveling ring 40 provided with circular rack 41 carries a bracket 42 upon which is j ournaled a wheel 43 provided with radial pins 44 which may be engaged by the goods or machine product for rotation in the direction of the arrow shown in Fig. 5'. Rotating with the wheel 43 is a bevel gear 45 which meshes with a second bevel gear 46 keyed to the upper end of a feed screw 47 which is journaled in a bearing 48 and supported vertically by means of a collar 49. On the lower end of the feed screw 47 is an adjustable abutment 50 which may be set to any desired osition to limit the downward movement 0 the indicator nut 51 which slidably engages a scale rod 52 which is adjustably mounted in a socket 53 which is preferably rigidly connected to the bearing 43. The operation of this modification is somewhat similar to the first embodiment, and is as follows:

. As the goods or product are passed from the machine, they engage the wheel 43 and thus serve to rotate the feed screw 47. The indicator nut 51, as it moves upwardly, indicates its travel on the scale bar 52. Eventually it is brought into engagement with lever or dog 54 whichis pivoted at 55 within a lug 56 carried by the bracket 42. The lever arm 54 is provided with a nose or shoulder 57 adapted to engage in the recess 58 in a I sleeve 59 and reciprocates on a post 60, being limited in its movement by-means of a pin 61 carried by the post 60 and which slides in a slot 62 in the sleeve 59. It will be understood from this description that as the indicator nut 51 nears the upper end of its movement, the parts assume relative positions shown in dotted lines in Fig. 5, which releases the sleeve 59. Whenever the sleeve 59 is released it drops into position to come into engagement with the cut-out lever 63 which is pivoted on the post 64 and operates a pin or bolt 65 carried by a slidable ring 66 which stops the machine. As shown in Figs. 5 and 6, the invention is particularly adapted for attachment to machines having small lateral extent.

The operation of my improved measuring device is Substantially the same for both embodiments. Thus, as the finished product,

' 59 to drop so that its new path of movement brings it into engagement with the lever 37 or 63 which imparts the belt shifting movethe ring 6 or 66 and stops the ma;
